* AT91: Change nand buswidth logic to match hardware default configurationNicolas Ferre2011-07-04
| | | | | | | | | | | | | | The recently modified nand buswitth configuration is not aligned with board reality: the double footprint on boards is always populated with 8bits buswidth nand flashes. So we have to consider that without particular configuration the 8bits buswidth is selected by default. Moreover, the previous logic was always using !board_have_nand_8bit(), we change it to a simpler: board_have_nand_16bit().

* arm: remove machine_desc.io_pg_offst and .phys_ioNicolas Pitre2010-10-20
| | | | | | | | | | | | | | | Since we're now using addruart to establish the debug mapping, we can remove the io_pg_offst and phys_io members of struct machine_desc. The various declarations were removed using the following script: grep -rl MACHINE_START arch/arm | xargs \ sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }' [ Initial patch was from Jeremy Kerr, example script from Russell King ] Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org> Acked-by: Eric Miao <eric.miao at canonical.com>

| * Fix rename of at91_nand -> atmel_nandPieter du Preez2008-08-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Structs called at91_nand_data where renamed to atmel_nand_data and configs called *MTD_NAND_AT91* where renamed to *MTD_NAND_ATMEL*. This was unfortunately not done consistently, causing NAND chips not being initialised on several ARM boards. I am aware that the author of the original change did not rename MTD_NAND_AT91_BUSWIDTH to MTD_NAND_ATMEL_BUSWIDTH, for example. All *MTD_NAND_AT91* where renamed to *MTD_NAND_ATMEL* in order to keep naming consistency. This patch was only tested on a MACH_SAM9_L9260, as this is the only ARM board I have to my disposal.

This patch splits the existing include/asm-arm/arch-at91/at91sam926x_mc.h into at91sam9_sdramc.h and at91sam9_smc.h. It also adds an at91cap9_ddrsdr.h for the DDRSDRC controller.

| | | | | | | | | | | | | | | | | The AT91 I2C driver is currently marked as "broken" due to hardware issues. This patch enables AT91-based platforms to also use the bitbanged GPIO for I2C. This updates platform setup logic (setting up an i2c-gpio device using the same pins as the i2c-at91 device, unless only the BROKEN driver is enabled). Also make use of the new-style initialization of I2C devices using i2c_register_board_info().

* [ARM] fix section mismatch warning in board-sam9260Sam Ravnborg2007-04-28
| | | | | | | | | | | | | | | | | | | | | Andrew Morton found a section mismatch warning in x86_64 triggered by a wrongly placed __initdata marker. git grep "struct __initdata" revealed that board-sam9260.c had the same problem. This patch fixes this by placing the __initdata marker correct. It was checked with objdump that the variable was moved to .init.data by this change. Fixed an unrelated section mismatch warning while touching the file. Both changes are only compile tested but obvious correct.

* [ARM] 4143/1: AT91: Prepare for AT91SAM9263 supportAndrew Victor2007-02-08
| | | | | | | | | | | | | | | | | | | | | The Atmel AT91SAM9263 processor includes many more integrated peripherals than Atmel's previous ARM9-based AT91 processors, so this has necessitated a few changes to the core AT91 support. These changes are: * The system peripheral I/O region we remap has increased from 0xFFFA0000..0xFFFFFFFF to 0xFFF78000..0xFFFFFFFF. * The increased I/O region forces changes to entry-macro.S and debug-macro.S due to ARM's limited immediate offset addressing modes. * Maximum number of GPIO banks increases to 5. * 2 MMC controllers so the board-setup code needs to specify which controller it wishes to use when calling at91_add_device_mmc().

* [ARM] 4124/1: Rename mach-at91rm9200 and arch-at91rm9200 directoriesAndrew Victor2007-02-08
Now that Linux includes support for the Atmel AT91SAM9260 and AT91SAM9261 processors in addition to the original Atmel AT91RM9200 (with support for more AT91 processors pending), the "mach-at91rm9200" and "arch-at91rm9200" directories should be renamed to indicate their more generic nature. The following git commands should be run BEFORE applying this patch: git-mv arch/arm/mach-at91rm9200 arch/arm/mach-at91 git-mv include/asm-arm/arch-at91rm9200 include/asm-arm/arch-at91 Signed-off-by: Andrew Victor <andrew@sanpeople.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
